To all whom it may concern:

Be it known that I, FRIEDRICH CORRELL, a subject of the Emperor of Germany, and residing at Frankfort-on-the-Main, Germany, have invented new and useful Improvements in Means for Collecting and Removing FloatingDbris and the Like in Rivers, Canals, and other Streams, (and for which patents have been obtained as follows: in Germany October 23,1889, No. 52,981; in Switzerland November 1r, 1889, No. 1,589; in Austria-Hungary February 26, 1890, No. 19,416 and No. 5,051; in Belgium January 14:, 1890, No. 89,170; in England January 11, 1890, No. 565, and in France April 22, 1890, No. 205,220,) of which the following is a specification.

This invention relates to an apparatus for collecting and removing debris and the like in rivers, canals, and other streams, and is especially adapted for use in connection with water-wheels, turbines, and pumps for the purpose of preventing foreign matter from entering and clogging them.

My apparatus consists, essentially, of a grating extending from the bottom of the stream to some distance above the surface thereof and of a rake or comb entering the spaces between the grating-bars and clearing the same of the debris which is carried to them by the water. The upper ends of the grating-bars are turned backward and downward to a platform to allow the dbris to be carried over them, fall down, and be collected on the platform. The teeth of the comb enter the spaces between the grating-bars from behind and stand out with their tips at the front side. The comb is moved from the bottom of the stream along the bars to a point near the platform where the teeth leave the grating. I

In order to enable everybody skilled in the art to carry into practice my inventioml will describe it more particularly,reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of an apparatus embodying my invention. Fig. 2 is a front elevation of the same. Figs. 3 and 4; are views of the inner and outer sides of one of the end supporting-standards of the apparatus.

Similar letters refer to similar parts in all the figures.

A A are the standards secured to the side walls of the canal and carrying the crosspieces B and O, to which the ends of the grating-bars a are fastened in any suitable way. I prefer to give an inclination to the straight portion of the bars and to bend the upper parts a and a in a way that the debris gathered by the comb-teeth at the front side of the bars is carried over it and falls down by itself when released of the pressure of the comb.

b h are the comb-teeth fitted to a bar 0, the ends of which bar are formed into or provided with guide-blocks c 0', moving in guidegrooves d made in the standards A, whereby the teeth I) of the comb are prevented from being pushed backward or borne down or tipped over by the pressure of the material.

6 e are the chains on which the bar 0 is mounted, as shown at c, and f f are the chainwheels which carry the chains, the wheels f being mounted on a revolving shaft h and the wheels f mounted on pivots or studs f. The bearings 2' of the shaft h are adjustable in slots 1" in the standards A. A to match any lengthening of the chains and to regulate their tightness by turning the adjustingscrews 70, passing through bars or plates t secured to lugs t on said standards. The shaft 71. may be rotated by hand or by power, as indicated in Fig. 2, where I show gear h,

belt 7L5.

\Vhenever a great height of the grating is required I prefer to attach several combs to the chains, so that one comb at least will be between the bars of the grating at any time and prevent them from being bent sidewise. The teeth of the comb are made of considerable thickness at the base, so as to present an inclined plane upward and to facilitate the removal of substances-such as pieces of wood-which otherwise might be jammed in between the bars. The bar 0, carrying the comb, moves upward at the back of the grat ing, and the teeth pass between the bars of the same and carry all dirt, leaves, Wood, 850., which are collecting at the front side to the pinion 712 on shaft 71 pulley h and power- I top. As the comb moves farther it shores the material over the circular part a of the bars to the parta where it slides down to the platform at by its own weight while the adhering water is dropping oil. The comb then passes downward and, gradually quitting the part a of the grating-bars, leaves all foreign matters behind. get cleared and enter the grating again at its bottom after awhile. The material gathering on the platform may be carried away from time to time.

\Vhen the side walls of the canal allow of it, the solid standards A may be replaced by simple guide rails or bars for the bar c. If i the canal is very broad, intermediary standards must be placed amid the stream and fixed at the bottom thereof and stiffened against each other by tie-bars. Additional guides for the bar 0 may be arranged it the same is necessary.

Vhenever it seems advisable to remove the entire grating in the winter or when it gets impracticable for other reasons I prefer to arrange the whole grating swinging around ashaft and to turn it upward outside the water whenever it is required.

The teeth of the comb thus I I am aware that there have been mechanical cleaning apparatuses; but Ido not think that there has been any furnished with a comb at the back of the grating. '75 i 'hat- I claim, and desire to soon re by Letters Patent, is-

1. The combination, with a grating, of a comb whose teeth enter between the gratingbars from the back and of means to move the comb along the bars.

The eombinatiomwith grating-bars having their upper ends curved backward and downward, of a platform and of a comb and means to move the latter, substantially as described.

l. The combination, with a grating having the upper ends of its bars curved backward, of one or more combs and of chains and chainwheels carrying the same, substantially as and for the purpose specified. i In testimony whereof I have signed my name to this specification in the presence of 5 two subscribing witnesses.
